Build fails: relocation R_X86_64_32 against `.bss' can not be used when making a shared object

[shrx]

$ make avx

I tried modifying the relevant code in Makefile:

ifeq ($(avx), enable)
gpuirr.o: gpuirr.s
	$(CXX) -fPIC -c $^ -o $@

But it results in the same error.

This issue is related to the SIMD library AVX and SSE.
First please check your computer enviroment. Whether your CPU support AVX and SSE.
The following steps help you to identify:

1. in terminal shell:
   egrep avx /proc/cpuinfo
2. if it return any lines. Thus means your CPU support AVX. You can use the same way to check SSE

IF the avx/sse are detected but the compiling still failed, then please check your gcc version by
gcc --version
if the gcc version is too low, the avx and sse may not be supported. The suggestion is to use version >= 4.4

If these cannot help, please let me know
